When i run Bonnie, this is the output: bash-2.04$ bonnie File './Bonnie.248', size: 104857600 Writing with putc()...done Rewriting...done Writing intelligently...done Reading with getc()...done Reading intelligently...done Seeker 1...Seeker 2...Seeker 3...start 'em...done...done...done... -------Sequential Output-------- ---Sequential Input-- --Random-- -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks--- Machine MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU 100 4769 13.4 4814 4.1 5767 5.7 24421 100.0 239718 96.4 31833.2 199.6 bash-2.04$ This seems really bad to me, on a "normal" system i get measurements maybe 8 higher then this. What could be causing this? No use of DMA? How can i see whether it's using DMA? And how do i enable it? The SCSI Caching Raid controller is an Adaptec 2100s. Also, the creation of the 35Gb Raid array took 4 hours to complete. The server is going to be a database server. Could somebody please tell me what's going on?
